BIOGEOnet : Bryophytes occurrences in Wallonia

Study Extent

The data were mainly collected in Wallonia, from the early 1980s to the present day. Most of the data were collected by prospecting 4kmx4km IFBL squares with the aim of establishing a detailed regional inventory. The dataset also includes opportunistic observations and other records collected in more specific contexts, included BIOGEOnet database.

Sampling

IFBL prospecting is designed to establish an exhaustive picture of the square diversity of Bryophytes. The squares are not surveyed in their entirety and efforts are concentrated on the different types of habitats that are present. Each square has been surveyed for at least one full day, and this effort is adapted according to the difficulty of access and the species richness encountered.

Quality Control

Samples have been systematically collected for species that are difficult to identify or rare, and are kept in the herbarium of A.Sotiaux and in the herbarium of the University of Liège.

Method steps

1. Field prospection in different contexts.
2. Aggregation into the BIOGEOnet database.
3. Extraction to DarwinCore.

Bryophyta S.L. The dataset covers 726 taxa (695 species, 2 genera, 29 subspecies).

1. Bryophyta
   common name: Mosses s.s rank: phylum
2. Hepaticophyta
   common name: Liverworts rank: phylum
3. Anthocerotophyta
   common name: Hornworts rank: phylum

An overwhelming majority of the data comes from Wallonia. However, the dataset alsoincludes data from neighbouring regions and countries (Flanders, Luxembourg, France, etc.).
